Slight rough idle

Have been noticing my truck has been having a slight rough/miss at idle. It is very slight but enough to see it in the tach. You can feel it in the seat when sitting there. Runs and drives great, pulled my trailer all week with no problems. Any suggestions?

Has a fresh oil change.

Did you check your 42 pin wire harness for any chaffing? Have you ever done the .50 mod? Check the 9 pin connector.

Seth has your coolant level dropped ? Is it smoking in the morning when you start it ? I am asking because it could also be an injector oring or injector cup leaking. But like Rob said start by checking the wiring harness.
